General information

1.4 General functional description

Angular increments are recorded via a pulse disk with a fixed number of cycles per
revolution. A scanning unit with an integrated optoelectronic system generates
electrical signals and emits pulses (measuring increments) which are pre-processed
at trigger stages.
The resolution of the measuring system is defined via the number of light/dark
segments (number of increments per revolution) on the pulse disk. For e.g. the
measuring system outputs a signal sequence of 8192 pulses per revolution.
In order to evaluate the code sequence, a 2
is output for the control.
The counter of an external control system can be reset with an additional zero pulse in
order to define the mechanical control reference point.
